Crystals Procurement Notes

Verify the specific suffix J indicates the 9 pF load capacitance requirement against the target circuit design. Confirm that the 0°C to +50°C operating range aligns with the environmental specifications of the end application. Ensure the PCB footprint matches the 5.00mm x 3.20mm dimensions and solder pad layout to guarantee reliable surface-mount attachment during manufacturing.

Crystals Selection Notes

Select this component when a 27 MHz reference with 9 pF load capacitance is required. The ±30 ppm tolerance suits general-purpose timing applications. Verify compatibility with the oscillator circuit's input impedance. Consider the 40 Ohm ESR value for drive level management. Ensure the industrial temperature range meets operational requirements.

Crystals Part Context

This component belongs to the CTS 445 series of surface-mount crystals. The series offers various frequency and package options for standard timing needs. The 445W3XJ variant specifically addresses designs requiring lower load capacitance values compared to standard 20 pF or 12 pF options. It utilizes a standard 4-SMD, no-lead package configuration common in compact electronics.
